v0.6.8-pre1

OptiScaler v0.6.8-pre1

Bugfix release

Added

• UseGenericAppIdWithDlss for DLSS preset overriding on games like Monster Hunter Rise (thanks to @MapleHinata) #72

Fixed

• DirectX 11 FSR 3.1.1 backend crash issue with old VC Runtime versions. (thanks to @MapleHinata) #70 #71

v0.7.0-pre9

OptiScaler v0.7.0-pre9

This build adds experimental Frame Generation support to v0.6.7 for DLSS supported games.
Instabiliy and crashes are possible, so be warned.

Frame Generation will not work if OptiScaler is used as nvngx.dll. Please follow these instructions.

Frame Generation Options

Frame Generaion

Enables & disables frame generation

Allow Async

Enables & disables async compution for frame generation which improves performance.
It usually cause crashes, so use at own risk

Debug View

Enables & disables FSR FG debug view.

Only Generated

When enabled only FG generated will be shown. Used for debug purposes.

HUD Fix

Enables & disables hudless image capturing.
It might cause crashes

• Limit option delays capturing hudless image for capturing correct image
• Extended option does not do much in it's current form. It might help in rare cases but hopefully it will shine in next releases.

When hudless image captured correctly you should see it in Debug View. Bottom middle image should not have any HUD elements.

Thanks to Artur, FakeMichau and RazzerBrazzer for helping me on testing this build.

v0.6.7

OptiScaler v0.6.7

Mistakenly uploaded pre14 as final, if you have downloaded this release before please redownload.

v0.6.0

OptiScaler v0.6.0

This release aims to improve the compatibility of the new in-game menu (especially when used with frame-gen) and add support for DLSS 3.7.

Added

• Added spoofing support for DLSS 3.7, usage description is below
• Added spoofing support when running as dxgi.dll (acts like d3d12-proxy).
• Added support for loading custom nvapi64.dll file when not working as nvngx.dll (from dll folder or user defined folder).

Fixed

• Tried to cover all frame-gen cases for the new in-game menu, hopefully it will be ok (There is a detection delay of about 170 frames, if the menu does not appear immediately after loading the game, please wait a bit after pressing the menu button)
• Fixed setting wrong internal rendering resolution during create feature (thanks to Sub & DARKERthanDA)
• Fixed when DLSS selected from ini was not applied when using DirectX 11 (thanks to ...Merlinch & wixuan)
• Fixed Motion Sharpness issues (thanks to Od1sseas)
• Increased the Motion Sharpness scale minimum to 0.1 to prevent division by zero problems (thanks to fakemichau).
• Added extra checks for Output Scaling and Display Size MV (Thanks to DARKERthanDA)
• Fixed reverting to initial upscaler on quality or resolution change when working with DLSS Enabler (thanks to fakemichau).
• Auto disable RCAS and Output Scaling on shader compilation issues, for linux check notes are at bottom (thanks to fakemichau).
• Fixed Output Scaling disabling conditions (Thanks to DARKERthanDA)
• Fixed conflicting preset selection & quality ratio when using DLSS (thanks to ...Merlinch?)
• Added yield() to /w Dx12 backend query wait spins, resulting in improved performance on Nvidia cards (thanks to DARKERthanDA)

Changed

• The structure of nvngx.ini has changed a bit, if your old settings are not applied, please compare with the new structure.

DLSS 3.7

This is only needed if you want to use OptiScaler solo (without DLSS Enabler or Uniscaler).

With DLSS 3.7 Nvidia disabled signature check override, this means nvngx.dll or _nvngx.dll must be signed by Nvidia. For this override I use a method developed by Artur (developer of DLSS Enabler). With this release, OptiScaler supports loading by these filenames:

• dxgi.dll (with Nvidia GPU spoofing)
• winmm.dll
• version.dll
• wininet.dll
• winhttp.dll
• OptiScaler.asi (with an ASI loader)

If there is another mod that uses the same filename (for example version.dll), if you rename it with -original suffix (for example version-original.dll), OptiScaler will load this file instead of the original library.

Step-by-step installation:

1. We need an Nvidia signed dll file to bypass signature checks. All games that support DLSS come with nvngx_dlss.dll. Most of the time it's in the games exe folder. Some games and engines keep these third party dll's in different folders (like plugins). So we need to find the nvngx_dlss.dll file and copy it to the games exe folder. If it's already in the games exe folder, make a copy of it.
2. Rename the copy of nvngx_dlss.dll in games exe folder to nvngx.dll.
3. Rename OptiScaler's nvngx.dll to one of the supported filenames (I prefer dxgi.dll, it also eliminates the need for d3d12 proxy) and copy it to the games exe folder.

That's it, now you should be able to run DLSS 3.7 games.

Please don't rename the ini file, it should stay as nvngx.ini.

Shader Compiling and Linux

If you are using OptiScaler with Linux and you have problems with RCAS or Output Scaling, you will probably see this message in your logs.

CompileShader error compiling shader : <anonymous>:83:26: E5005: Function "rcp" is not defined.

To solve this problem you need to install d3dcompiler_47 with WineTricks or ProtonTricks. OptiScaler uses custom shaders for these features and depends on this compiler file to compile these shaders at runtime.

Thanks to fakemichau for pointing out this solution.

As always thanks to all DLSS2FSR members for their help & support

v0.5.5

Added

• Added DLSS upscaling support, when using DLSS with OptiScaler you will have DLSS specific;

  • Control over DLSS presets (DLSS 3.x only)
  • Auto enabling DLSS support for 16XX GPUs
  • Added spoofing for GetFeatureRequirements
  • Override DLSS sharpening (up to DLSS 2.5.1)

• Also with DLSS you can use OptiScaler's;

  • Scaling overrides
  • Override DLSS init flags
  • In-game menu
  • RCAS sharpening (only on Dx12)
  • Output resolution scaling (only on Dx12)

• Added new in-game menu which works on all APIs and does not affected by games rendering pipeline. In case of compatibility issues (or for nostalgia 😅 ) old menu still can be enabled by setting OverlayMenu=false from nvngx.ini (Thanks to RazzerBrazzer, regar DARKERthanDA, Brutale1090, iamnotstanley and Od1sseas for all the testing).

  If you are using RTSS (MSI Afterburner, CapFrameX, etc) please enable Use Microsoft Detours API hooking from settings.
  

• Added Motion Sharpening option, which increases sharpening amount of pixels based on their motion. (RCAS only) (Thanks to Od1sseas)

• Added option to select RCAS for FSR upscalers (Dx12 and Dx11 with Dx12 only)

• Added an option to round internal resolution to desired number

• Added DRS (Dynamic Resolution Scaling) now have options to limit minimum or maximum resolution to render resolution.

• Added more integration options with DLSS Enabler

Changed

• XeSS upscaling library libxess.dll is not statically linked anymore. This means now even without libxess.dll mod works (ofc without XeSS support). With new ini option users can point a folder which contains library or even if game natively supports XeSS mod now uses library loaded by game. Also with limited testing I can confirm 2 different versions of XeSS libraries (for example game loads 1.2.0 and mod loads 1.3.0) coexist and work on same instance.
• CAS sharpening replaced with RCAS, which solves issues with bloom, glow and other effects etc.
• Super Sampling option evoled into Output Scaling, now it's working based on display resolution and in 0.5 - 3.0 scaling range. This allows users to set lower target resolutions than display resolutions which was requested by Deck users.
• Restructured in-game menu to show only currently available options to prevent confusion.
• DRS range limited to 0.5x - 1.0x to mimic Nvidia aproach

Fixed

• Sometimes DLSS upscaler had wrong motion vectors setup, now fixed (Thanks to DARKERthanDA)
• Some games were not releasing the mouse, now they should be fixed. (Cyberpunk 2077, Horizon Zero Dawn, etc.)
• Some games were not registering mouse clicks, now they should be fixed. (Doom Eternal) (Thanks to RazzerBrazzer)
• Dx11 XeSS libxess.dll not found fallback fixed
• Added controls for junk Vulkan DLSS init data and prevent crashes
• Added SDK version checks for logging options

Here are some examples from games that had problems with in-game menu (Thanks to RazzerBrazzer and DARKERthanDA for images)

Alan Wake 2	Star Wars Jedi: Survivor
Banishers: Ghosts of New Eden	INDIKA
Mortal Shell	Pools

And Vulkan games

No Man's Sky	Doom Eternal

v0.4.3

New:

• Added an in-game menu scaling option

Changed

• Added new options for Dx11wDx12 creation & syncing. I have tried to explain it here. These settings are game & hw dependant so users need to tweak and find best performing configuration for their system. I have set safe and balanced values as default values.

v0.4.2

New:

• XeSS now have a new parameter CreateHeaps (default true). When it's enabled OptiScaler internally create heap objects and bind them instead of relying XeSS to create them. This fixes Guardians of the Galaxy black screen with XeSS issue. (Thanks to RazzerBrazzer)

Fixed:

• Crysis 3 Remastered showing black screen w/Dx12 backends on non-Arc GPUs fixed. (Thanks to closesim & RazzerBrazzer)

Changed:

• Dx11wDx12 backends had a few seconds worth of delays to ensure stability and compatibility. After the improvements made in v0.4 release looks like these delays aren't necessary anymore. For compatiblity sake I have added a new parameter UseDelayedInit (default false) for enabling these delays again.
